AIRCRAFT SYSTEM AND METHOD FOR INDICATING
AVAILABLE COMMUNICATION CHANNELS
FIELD
This application relates to aircraft and, more particularly, to aircraft
wireless
communication.
BACKGROUND
Pilots of modern-day aircraft, including commercial aircraft and military
aircraft,
typically rely on various electronic devices, regardless of whether they are
on the
ground preparing for flight, in flight, or back on the ground after a flight.
Many such
electronic devices wirelessly transmit and receive data, such as with on-the-
ground
receivers and transmitters.
As an example, the electronic flight bag has replaced the heavy, paper-filled
flight
bag pilots typically carried in days past. A typical electronic flight bag is
a computing
device, such as a portable computer or tablet, that includes a display and
wireless
communication functionality. Therefore, the typical electronic flight bag is
capable of
transmitting and receiving data over various channels, such as cellular,
wireless
local area networks and satellite, and displaying sent and received data to
the pilot
by way of the display.
The electronic flight bag allows the pilot to perform various tasks, such as
executing
pre-flight check procedures, generating flight plans, performing take-off and
landing
calculations, and maintaining flight logs. The electronic flight bag also
stores and
displays various navigational charts, runway maps, manuals and other
documents.
Additionally, since the electronic flight bag is configured to wirelessly
transmit and
receive data, it offers pilots real-time information, such as weather reports,
air traffic
updates and the like.

DETAILED DESCRIPTION
Referring to Fig. 1, one embodiment of the disclosed aircraft system for
indicating
available communication channels, generally designated 10, may include an
aircraft
12 and an electronic instrument 14. The aircraft 12 may have a flight deck 16
and
the electronic instrument 14 may be on the flight deck 16 of the aircraft 12.
As shown in Fig. 2, the aircraft 12 may include an airframe 18 and an interior
20.
The airframe 18 of the aircraft 12 may include one or more high-level systems
22,
such as a propulsion system 24, an electrical system 26, a hydraulic system 28
and
an environmental system 30. The interior 20 of the aircraft 12 may include the
flight
deck 16 and, optionally, a passenger compartment and/or a cargo hold.
Referring back to Fig. 1, the electronic instrument 14 may include a processor
32,
data storage 34, an input device 36, an output device 38 and a wireless
connectivity
interface 40. The electronic instrument 14 may include fewer features or
additional

example, it
is contemplated that, in an alternative to the embodiment shown in Fig. 1, the
electronic instrument 14 may be configured without an input device 36.
¨4¨
CA 02887812 2015-04-10
The processor 32 may be in communication with the data storage 34, the input
device 36, the output device 38 and the wireless connectivity interface 40.
The
processor 32 may include one or more microprocessors and/or multi-core
processors, such as a central processing unit. The processor 32 may interpret
and
execute instructions to effect operation and use of the electronic instrument
14.
The data storage 34 may include volatile and/or non-volatile memory. For
example,

devices
36 include, but are not limited to, a keyboard, a keypad, a mouse, a pen, a
microphone, a touchscreen display, and the like.
The output device 38 may be any device that outputs information to the pilot
of the
aircraft 12. As described in greater detail herein, the output device 38 may
provide
to the pilot an indication of which (if any) of the communication channels 44
are
available. An "available" communication channel 44 may be a communication
channel 44 over which data is capable of being transmitted and/or received.
Additionally, as described in greater detail herein, the output device 38 may
provide
to the pilot an indication of which (if any) of the communication channels 44
are in
use, such as, for example, when only one available communication channel 44 is
permitted to be in use at any given time. An "in-use" communication channel 44
may be a communication channel 44 that is both available and actually being
used
to transmit and/or receive data.
¨5¨
CA 02887812 2015-04-10
In one particular realization, the output device 38 may include a display 42,
such as
a cathode ray tube (CRT) display, a liquid crystal display (LCD), a light
emitting
diode (LED) display, a plasma display or the like. The display 42 may provide
to the
pilot a visual indication 48 of which (if any) of the communication channels
44 are
available, as well as a visual indication 48 of which (if any) of the
communication
channels 44 are in use. Alternative output devices 38 include, but are not
limited to,
speakers, indicator lights, gauges, printing devices and the like.
The wireless connectivity interface 40 may be any feature, such as hardware or
a
combination of hardware and software, that facilitates wireless communication
over
one or more communication channels 44. For example, the wireless connectivity
interface 40 may facilitate wireless communication between the electronic
instrument
14 and various on-the-ground transmitters/receivers (e.g., an airline
management; a
weather reporting service; air traffic control).
In Fig. 1, the wireless connectivity interface 40 of the electronic instrument
14 is
shown with the capability to wirelessly communicate over three communication
channels 44, specifically a satellite communication channel 44A, a wireless
local
area network 44B and a cellular network 44C. However, the wireless
connectivity
interface 40 may be capable of communicating over fewer than three
communication
channels 44 or more than three communication channels 44 without departing
from
the scope of the present disclosure.
Furthermore, while the satellite communication channel 44A, the wireless local
area
network 44B and the cellular network 44C are shown and described as three
examples of communication channels 44, those skilled in the art will
appreciate that
the wireless connectivity interface 40 of the electronic instrument 14 may
facilitate
wireless communication over a broad variety of communication channels 44.
Other
examples of communication channels 44 include, but are not limited to, UHF
channels, VHF channels, HF channels, broadband, Gatelink, terminal wireless
LAN
unit (71/VLU"), aircraft communications addressing and reporting system
("ACARS").
¨6¨
CA 02887812 2015-04-10
As one general example, the electronic instrument 14 may be an electronic
flight
bag. As one specific, non-limiting example, the electronic instrument 14 may
be a
laptop computer-based electronic flight bag. As another specific, non-limiting
example, the electronic instrument 14 may be a tablet-based electronic flight
bag.
As another general example, the electronic instrument 14 may be an aircraft
instrument, such as a flight display. As one specific, non-limiting example,
the
electronic instrument 14 may be a primary flight display. As another specific,
non-
limiting example, the electronic instrument 14 may be a secondary flight
display.
Referring now to Fig. 3, in one particular implementation, the electronic
instrument
14 of the disclosed aircraft system 10 (Fig. 1) may be an electronic flight
bag 15 and
may include a display 42 (an output device 38) and one or more input devices
36
(e.g., scroll and selection buttons). To provide to the pilot a visual
indication 48 of
communication channels 44 (Fig. 1) that are available, icons 46 corresponding
to the
available communication channels 44 may be displayed on the display 42. For
example, the display of icon 46A on the display 42 may provide a visual
indication
48 that the satellite communication channel 44A is available, the display of
icon 46B
on the display 42 may provide a visual indication 48 that the wireless local
area
network 44B is available, and the display of icon 46C on the display 42 may
provide
a visual indication 48 that the cellular network 44C is available.
Icons 46 are one example of visual indications 48, specifically graphic visual
indications 48, contemplated by the present disclosure. Various other visual
indications 48, such as text, illumination (e.g., indicator lights) and other
graphical
visual indications (e.g., arrows), are also contemplated.
Still referring to Fig. 3, of the available communication channels 44A, 44B,
44C (Fig.
1), as represented by displayed icons 46A, 46B, 46C, only a limited number
(e.g.,
one) may be in use. There may be various reasons for placing in use only one
(or
several) of the available communication channels 44A, 44B, 44C. For example,
¨7¨
CA 02887812 2015-04-10
communication over each of the available communication channels 44A, 44B, 44C
may have a cost associated therewith, and only the communication channel 44
available at the lowest cost may be placed in use. Therefore, while the
satellite
communication channel 44A, the wireless local area network 44B and the
cellular
network 44C may be available, as shown by the display of icons 46A, 46B, 46C
in
Fig. 3, only the cellular network 44C may be in use, as shown by the
prominence of
icon 46C vis-à-vis the other icons 46A, 46B.
In Fig. 3, icon 460 is made prominent by graying out the other icons 46A, 46B.
However, those skilled in the art will appreciate that various techniques may
be used
to visually identify one icon 46C as being more prominent than the other icons
46A,
46B and, thus, indicative of the communication channel 44C (Fig. 1) that is in
use.
Prominence may be effected by emphasizing icon 46C and/or deemphasizing icons
46A, 46B. Emphasis and de-emphasis may be added in various ways, such as by
bolding one or more icons, graying-out one or more icons, coloring one or more
icons (e.g., icon 46C may be green, while icons 46A, 46B may be red), or the
like.
Thus, the upper right corner of the display 42 of the electronic instrument 14
shown
in Fig. 3 may provide a visual indication 48 to the pilot that three
communication
channels 44 (Fig. 1) are available, specifically the satellite communication
channel
44A (indicated by icon 46A), the wireless local area network 44B (indicated by
icon
46B) and the cellular network 44C (indicated by icon 46C), but that only the
cellular
network 44C is in use (indicated by the prominence of icon 46C relative to
deemphasized icons 46A, 46B).
Referring to Fig. 4, in one alternative, the upper right corner of the display
42 of the
electronic instrument 14 may provide a visual indication 48 to the pilot that
three
communication channels 44 (Fig. 1) are available, specifically the satellite
communication channel 44A (indicated by icon 46A), the wireless local area
network
44B (indicated by icon 46B) and the cellular network 44C (indicated by icon
460),
¨8¨
CA 02887812 2015-04-10
but that only the wireless local area network 44B is in use (indicated by the
prominence of icon 46B relative to deemphasized icons 46A, 46C).
Referring to Fig. 5, in another alternative, the upper right corner of the
display 42 of
the electronic instrument 14 may provide a visual indication 48 to the pilot
that two
communication channels 44 (Fig. 1) are available, specifically the satellite
communication channel 44A (indicated by icon 46A) and the cellular network 44C
(indicated by icon 46C), but that only the satellite communication channel 44A
is in
use (indicated by the prominence of icon 46A relative to deemphasized icon
46C).
As shown in Figs. 3-5, the visual indication 48 of communication channels 44
(Fig.
1) that are available and in use may appear on the "Main Menu" page. However,
the
display 42 of the electronic instrument 14 may be capable of displaying
various
pages, such as a "Maps" page, a "Charts" page, a "Documents" page, and a
"Systems Page," in addition to the "Main Menu" page. In one optional
variation,
such as when distraction is a concern, the visual indication 48 may only be
displayed
on one or more of the pages accessible by way of the "Main Menu" page, such as
only on the "Systems Page"¨not on the "Main Menu" page.
Also disclosed is a method for indicating available communication channels on
an
aircraft. Referring to Fig. 6, one embodiment of the disclosed method,
generally
designated 100, may begin at Block 102 with the step of providing an
electronic
instrument with wireless connectivity over at least one wireless communication
channel. The electronic instrument may be an electronic flight bag or the
like, and
may be on the flight deck of the aircraft.
At Block 104, the communication channels available to the electronic
instrument
may be ascertained. For example, if the electronic instrument includes a
wireless
connectivity interface that facilitates wireless communication over three
communication channels, at Block 104 the method 100 may ascertain which, if
any,
of the three communication channels are available.
¨9¨
CA 02887812 2015-04-10
At Block 106, the in-use communication channel (or channels), if any, of the
available communication channels may be ascertained. For example, if two
communication channels are available, but only one of the available
communication
channels is in use (e.g., when only the lower cost communication channel is
being
used), the method 100 (at Block 106) may ascertain which communication channel
is in use.
At Block 108, a visual indication of the available communication channels, if
any,
and in-use available communication channels, if any, is provided. For example,
the
step of providing a visual indication (Block 108) may include instructing a
display of
the electronic instrument to display icons indicative of the available
communication
channels (if any) and the in-use available communication channels (if any).
Accordingly, the disclosed aircraft system 10 and method 100 may provide
aircraft
pilots with a quick and readily accessible indication, such as a visual
indication (e.g.,
one or more icons), of the available and in-use communication channels for an
electronic instrument, such as an electronic flight bag. Therefore, pilots may
use the
indication (e.g., visual indication) to prioritize tasks. For example, a pilot
may refrain
from using the electronic device when no communication channels are available.
Additionally, the indication may provide pilots more information in the
currency of the
data being wirelessly transmitted to the electronic device.
Although various embodiments of the disclosed aircraft system and method for
indicating available communication channels have been shown and described,
modifications may occur to those skilled in the art upon reading the
specification.
The present application contemplates and includes such modifications, and is
limited
only by the scope of the claims.
